Answer:

According to this figure .

7x-2=6x+18

x=20

Step by Step Explanation:

7x-2+y=180

y=180-138

therefore angle 1 is equal to 42 degrees

<h3>Answer: 42 degrees (choice B)</h3>

=================================

How I got this answer:

The alternate exterior angles (7x-2) and (6x+18) are congruent due to the fact that line s is parallel to line t.

Set the two expressions equal to one another. Solve for x

7x-2 = 6x+18

7x-2+2 = 6x+18+2 .... adding 2 to both sides

7x = 6x+20

7x-6x = 6x+20-6x .... subtracting 6x from both sides

x = 20

----------

If x = 20, then we can find the measure of angle (7x-2)

7x-2 = 7*20-2 = 140-2 = 138

As a check, let's see what angle (6x+18) is too

6x+18 = 6*20+18 = 120+18 = 138

We get the same result for each angle, so that confirms x = 20 is correct.

------------

Since angle (7x-2) is 138 degrees, this means

angle 1 = 180 - (7x-2)

angle 1 = 180 - 138

angle 1 = 42 degrees

The points (-1.6, 2.7) and (3.2, 7.98) are on the graph of a linear relationship between two variables, r and y.

Answer:

y = 1.1x +4.46

y = 129.86 for x = 114

Step-by-step explanation:

The two-point form of the the equation for a line is useful for this.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (7.98 -2.7)/(3.2 -(-1.6))(x -(-1.6)) + 2.7

y = 5.28/4.8(x +1.6) + 2.7

y = 1.1x +1.76 +2.7

y = 1.1x +4.46

When x=114, the value of y is ...

y = 1.1(114) +4.46

y = 129.86

It would be J. This is because the opposite of -3.5 would be 3.5 and the absolute value is just a positive integer or positive number so that would be 3.5 as well so its J

1. Which of the following questions has a constant of

garik1379 [7]

Answer:

In B) y = x/7 , the constant of proportionality is 7.

Step-by-step explanation:

Two quantities X and Y are said to be in proportion if and only if

X = kY or, $\frac{X}{Y} = k$ ,

where k = Proportionality Constant.

Here, 7 is the constant of proportionality. Then,

A . y = 14x

here, $\frac{y}{x} = 14$ ≠ 7

B . y = x/7

here, $\frac{x}{y} = 7$ = constant of proportionality .

C. y = x

here, $\frac{y}{x} = 1$ ≠ 7

Dave has 12$ to spend on a 7 dollar book and two birthday cards (c) for his friends how much can he spend on each card if he buy

anzhelika [568]

Answer:

2.50

Step-by-step explanation:

So if you have a budget of 12 dollars, and the book is 7 dollars, subtract 12-7 and you get 5 dollars. And half of 5 dollars is 2.50. And if there is 2 cards, then that means that 1 card is 2.50
